Appendix A_2008-18430 SPL - Pre-lodgement advice (1)

                                                                                               2008-18430 SPL



   PO5 The timing of works avoids marine plant flowering, fish spawning and fish migration periods.
      The proposed works will need to be scheduled to avoid the peak spawning and migration times
       for common recreational and commercial fish species (incl. Whiting, flathead, sea mullet and
       some prawn species) that are known to spawn in / migrate through, estuarine waters.

   PO6 – To meet this PO provide evidence that demonstrates the impacts arising from the dredging
   and nourishment works have been considered and will be managed to avoid the unnecessary loss,
   degradation or fragmentation of marine plants, fish and fish habitats in the vicinity of the works.
      An application should discuss buffer zones and the proximity of the declared Noosa River Fish
       Habitat Area to the dredge channel; beach replenishment and sand plug design; and the
       management of dredge plumes and water quality.

   PO7 – Development does not increase the risk of mortality, disease or injury, or compromise the
   health, productivity, marketability or suitability for human consumption of fisheries resources, having
   regard to (but not limited to):
   a) biotic and abiotic conditions, such as water and sediment quality
   b) substances that are toxic to plants or toxic to or cumulative within fish
   c) design of structures
   d) impacts on reproductive success
   e) effect on fish energy reserves
   f) whether fish may be physically damaged, killed, trapped or stranded
   g) fish passage and access to habitats generally, and
   h) the impacts of pest fish and other relevant pest species.

  Given the proximity of the proposed dredge extraction area to a declared FHA, management ‘A’ area,
  information must be provided detailing how the proposed dredge and beach nourishment operations
  will be managed to avoid impacts in relation to items 1, 2, 4 and 6 in particular (ties in with PO’s 5, 6 &
  9).

   PO9 – If acid sulfate soils are present within the proposed dredge footprint provide evidence that
   demonstrates they will be managed according to current best practice. If necessary, discuss soil
   transfer and treatment locations.

   PO10 and PO11 – The proposed works will modify tidal and freshwater inundation patterns and the
   natural processes of accretion and erosion. To meet these PO’s it will be necessary to provide a
   performance solution that demonstrates the proposed works are:
    justifiable in terms of project outcomes
    the least impact option with respect to fish habitats
    are designed to minimise construction and future impacts on marine plant and fish habitats, and
    include a post-works monitoring plan that provides for marine plants in the vicinity of the works
    demonstrate that the proposed sand extraction and beach nourishment will not result in the
       transfer of severe erosive conditions to a new part of the estuary, and
    demonstrate that the proposed design is sustainable i.e. will result in the least frequent
       maintenance requirements of all considered options.

   In accordance with PO12 the proposed works will need to be designed, sited and constructed to
   ensure its long-term use and operability will not result in on-going (or new) adverse impacts or
   additional development including dredging to maintain access.

   Dredging and beach nourishment works should not cause or require further works to be conducted
   that will have adverse ongoing or additional impacts on marine plants. An application is required to
   demonstrate that the proposed works have considered and avoided / mitigated ongoing impacts to
   marine plants and fish habitat post construction, e.g. Via ongoing maintenance to ensure works
   achieve the required need. A post-works monitoring plan with an alert/action commitment should be
   discussed here.
